Fix Textpattern: Resolve the preg_replace() Error

The latest version of Textpattern CMS, 4.5.5 as I write this, trips up on PHP 5.5. In my previous post I explained how to solve the `yield` error that is thrown up with Textpattern 4.5.5 and PHP 5.5, and this article is in a similar vein. If you run Textpattern 4.5.5 alongside PHP 5.5, you will likely see this error at some stage:

Note that the error will occur only in the admin-side of Textpattern, your users will not be shown a bewildering error and be scared off. Additionally, the error will be thrown up when the following criteria are met:

the site is in Testing or Debugging mode

an article is posted or updated

The culprit in this case is Textile, the markup generator baked into Textpattern. When sporadic reports of this problem were reported in late 2013, a fix was created and Textile was updated to resolve the problem. As such, the solution to the `preg_replace` error is to drop in the updated Textile file from the issue tracker here. When this file is replaced with the updated version, the `preg_replace` errors will no longer appear.
